I once encountered a starter failure when my Mercedes made strange noises upon starting, feeling like it was about to give up. I checked if the battery voltage was sufficient, as low charge is often the culprit. Using a multimeter, I found that the voltage was indeed below 12 volts when the problem occurred. If you notice slow cranking or clicking sounds, avoid forcing multiple ignition attempts to prevent damaging components. Try cleaning the terminal posts or replacing the fuse. It's advisable to take it to a professional shop for diagnosis as soon as possible—they can test whether the starter motor has worn carbon brushes or stuck gears. Regular maintenance, such as parking in a dry place and checking the battery monthly, can significantly extend its lifespan. Most importantly, don’t delay. If the car stalls on the road, pull over safely and turn on the hazard lights. Mercedes parts are expensive, but the repair is worth it for several more years of driving.
